WARNING: Both natural gas and propane have an
odorant added to aid in detecting a gas leak. Some
people may not physically be able to smell or
recognize this odorant. If you are unsure or
unfamiliar with the smell of natural gas or propane,
ask your local gas supplier. Other conditions, such
as "odorant fade," which causes the odorant to
diminish in intensity, can also hide, camouflage, or
otherwise make detecting a gas leak by smell more
difficult.
WARNING: Do not install within 3 feet (0.9 m) of a
heat pump or an outdoor condensing unit. Strong air
intake from this type of equipment can disturb the
combustion process and cause damage or personal
injury.
WARNING: UL recognized fuel gas detectors are
recommended in all enclosed propane and natural
gas applications wherein there is a potential for an
explosive mixture of fuel gas to accumulate and their
installation should be in accordance with the
detector manufacturer's recommendations and/or
local laws, rules, regulations, or customs.
WARNING: The heater shall not be located in an
area where water sprinklers, or other devices, may
cause water to spray through the cabinet louvers and
into the heater. This could cause internal rusting or
damage electrical components, and void the warran-
ty.

WATER CHEMISTRY
Chemical imbalance can cause severe damage to
your heater and associated equipment. Maintain your
water chemistry according to Table A. If the mineral
content and dissolved solids in the water become too
high, scale forms inside the heat exchanger tubes,
reducing heater efficiency and damaging the heater. If
the pH drops below 7.2, this will cause corrosion of the
heat exchanger and severely damage the heater. Heat
exchanger damage resulting from chemical imbal-
ance is not covered by the warranty.
For your health and the protection of your pool equip-
ment, it is essential that your water be chemically
balanced. The following levels must be used as a
guide for balanced water.
• Occasional chemical shock dosing of the pool or
spa water should not damage the heater providing
the water is balanced.
• Automatic chemical dosing devices and salt chlo-
rinators are usually more efficient in heated water,
unless controlled, they can lead to excessive chlo-
rine level which can damage your heater.
• Further advice should be obtained from your pool
or spa builder, accredited pool shop, or chemical
supplier for the correct levels for your water.
Automatic Chlorinators &
Chemical Feeders
All chemicals must be introduced and completely dilut-
ed into the pool or spa water before being circulated
through the heater. Do not place sanitizing chemi-
cals in the skimmer. High chemical concentrations
will result when the pump is not running (e.g.
overnight).
Chlorinators must feed downstream of the heater and
have an anti-siphoning device to prevent chemical
back-up into the heater when the pump is shut off. See
Fig. 1.
NOTE: Corrosive water voids all warranties.
CAUTION: Free chlorine must not exceed 5 ppm
which can damage the heater and is not covered
under warranty.
NOTE: High chemical concentrates from feeders
and chlorinators that are out of adjustment will
cause rapid corrosion to the heat exchanger.
Such damage is not covered under the warranty.

SAFETY
This appliance is to be installed and operated by
trained personnel in accordance with this Installation
and Operation Manual. Be sure to read and under-
stand the entire Installation and Operation Manual
before attempting to install or operate this appliance.
Failure to follow the warnings listed at the beginning of
this manual could result in a fire or explosion, causing
property damage, bodily injury, or death.
Should you have any problems understanding the
warnings and instructions in this manual, STOP, and
get help from a qualified installer, service technician,

Water Temperature Safety
Elevated water temperature can be hazardous. The
U.S. Consumer Product Safety Commission has these
guidelines:
1. Spa water temperatures should never exceed
104°F (40°C). A temperature of 100°F (38°C) is
considered safe for a healthy adult. Special cau-
tion is suggested for young children.
2. Drinking of alcoholic beverages before or during
spa or hot tub use may cause drowsiness which
could lead to unconsciousness and subsequently
result in drowning.
3. Pregnant Women Beware! Soaking in water over
102°F (39°C) may cause fetal damage during the
first three months of pregnancy resulting in the
birth of a brain-damaged or deformed child.
Pregnant women should stick to the 100°F (38°C)
maximum rule.
4. Before entering the spa or hot tub, users should
check the water temperature with an accurate
thermometer; spa or hot tub thermostats may err
in regulating water temperatures by as much as
4°F (2.2°C).
5. Persons with a medical history of heart disease,
circulatory problems, diabetes, or blood pressure
problems should obtain a physician's advice
before using spas or hot tubs.
6. Persons taking medications which induce drowsi-
ness, such as tranquilizers, antihistamines,
anticoagulants, or recreational drugs should not
use spas or hot tubs.

CALIFORNIA PROPOSITION 65 WARNING: This product contains chemicals known to the State of California
to cause cancer, birth defects or other reproductive harm.
IMPORTANT NOTICE
These instructions are intended only for the use by qualified personnel, specifically trained and experi-
enced in the installation of this type of heating equipment and related system components. Installation
and service personnel may be required by some states to be licensed. If your state is such, be sure your con-
tractor bears the appropriate license. Persons not qualified shall not attempt to fix this equipment nor attempt
repairs according to these instructions.
WARNING: Improper installation, adjustment, alteration, service or maintenance may damage the equip-
ment, create a hazard resulting in asphyxiation, explosion or fire, and will void the warranty.
WARNING: This unit contains refractory ceramic fiber (RCF) insulation in the combustion chamber. RCF, as
manufactured, does not contain respirable crystalline silica. However, following sustained exposure to very
high temperatures (>2192F), the RCF can transform into crystalline silica (cristabolite). The International
Agency for Research on Cancer (IARC) has classified the inhalation of crystalline silica (cristabolite) as car-
cinogenic to humans.
When removing the burners or heat exchangers, take precautions to avoid creating airborne dust and avoid
inhaling airborne fibers. When cleaning spills, use wet sweeping or High Efficiency Particulate Air (HEPA)
filtered vacuum to minimize airborne dust. Use feasible engineering controls such as local exhaust ventilation
or dust collecting systems to minimize airborne dust. Wear appropriate personal protective equipment
including gloves, safety glasses with side shields, and appropriate NIOSH certified respiratory protection, to
avoid inhalation of airborne dust and airborne fiber particles.

Combustion & Ventilation Air
(Indoor Units Only)
The heater must have both combustion and ventilation
air. Minimum requirements for net free air supply
openings are one opening that is 12 inches (30.5 cm)
from the ceiling for ventilation, and one opening that is
12 inches (30.5 cm) from the floor for combustion air
as outlined in the latest edition of the National Fuel
Gas Code, ANSI Z223.1 (Canada-CAN/CSA-B149)
and any local codes that may have jurisdiction.
NOTE: For Canada, indoor installation is restricted
to an enclosure that is not occupied and does not
directly communicate with an occupied area. Refer
to the latest edition of CAN/CSA-B149 for specific
requirements.
All Air from inside the building each opening shall•
have a minimum net free area as noted in Table E.
All air from outdoors when air is supplied directly•
from outside the building each opening shall have
a minimum net free area as noted in Table D.
Vent Piping
Vent piping the same size as the drafthood outlet is
recommended, however, when the total vent height is
at least 10 ft (3m) (drafthood relief opening to vent ter-
minal), the vent pipe size may be reduced as specified
in the National Fuel Gas Code, ANSI Z223.1 (Canada
- CAN/CSA-B149). As much as possible, avoid long
horizontal runs of vent pipe and too many elbows.
If installation requires horizontal runs, the vent pipe
must have a minimum of 1/4 in. (2cm per m) per ft rise
and should be supported at not more than five foot
intervals. Plumbers tape, criss-crossed, will serve to
space both horizontal and vertical piping. Gas vents
supported only by the flashing and extending above
the roof more than 5 ft (1.5m) should be securely
guyed or braced to withstand snow and wind loads.
We recommend use of insulated vent pipe spacers
through the roof and walls.
For protection against rain or blockage by snow, the
vent pipe must terminate with a vent cap which com-
plies with local codes or, in the absence of such codes,
the latest edition of the National Fuel Gas Code, ANSI
Z223.1 (Canada - CAN/CSA-B149).
WARNING: Indoor heaters require a drafthood
that must be connected to a vent ppe and properly
vented to the outside. Failure to follow this
procedure can cause fire or fatal carbon monoxide
poisoning.

Pipe Sizing for Gas Connections
Water Connections
The heater requires water flow and positive pressure
to fire and operate properly. It must therefore be
installed downstream of the discharge side of the filter
pump. A typical installation is plumbed as follows:
1. The inlet side of the filter is plumbed directly to the
discharge side of the filter pump;
2. The outlet side of the filter is then plumbed to the
inlet of the heater; and
3. The outlet of the heater is plumbed to the return
line to the pool or spa. The pump, filter and heater
are thus plumbed in series.
Plumbing from the heater back to the pool or spa must
not have any valves or restriction that could prevent
flow when the pump is operating.
Heater must be located so that any water leaks will not
damage the structure of adjacent area. PVC pipe may
be glued directly into supplied CPVC header unions.

Before attaching the supplied 2-inch (5 cm) CPVC
unions to the In/Out header, make sure the O-rings are
properly seated in the grooves. Use AquaLube or
equivalent non-petroleum-based lubricant on the O-
ring. Hand tighten the unions. Glue PVC or CPVC
piping directly to the unions.

If there is any possibility of back-siphoning when the
pump stops, it is recommended that a check valve (or
valves) also be installed in the system.
Internal Automatic Bypass Valve
A built-in automatic bypass valve is provided in the
In/Out header. The internal bypass valve automatical-
ly responds to changes in water pressure in the piping
system. The proper amount of water flow is maintained
through the heater under varying pressures dictated
by the conditions of the pump and filter.
External Auxiliary Bypass Valve
An auxiliary bypass valve must be used when flow
rates exceed 70 GPM (265 LPM). Usually a high-per-
formance pump size larger than one horsepower will
exceed this flow rate. This valve is required to comple-
ment the function of the automatic bypass valve,
particularly when starting the heater in winter or early
spring when the spa or pool temperature is below 50°F
(10°C). It also serves to eliminate needless pressure
drop through the heater and accompanying reduction
in the flow rate to the spa jets, etc.

Auxiliary Bypass Valve Adjustment
To set bypass: With clean filter, adjustment is made by
feeling the inlet and outlet pipes at the heater. Outlet
pipes should be slightly warmer than inlet and comfort-
able to the touch. If pipe is hot, close bypass; if cold,
open bypass.
Pressure Relief Valve Installation
To conform to local building codes, it may be neces-
sary to install a pressure relief valve. A 3/4" (1.9 cm)
pressure relief valve, having a capacity equal to or
greater than the BTUH input of the heater to be
installed, is recommended for this heater. The maxi-
mum pressure relief valve setting is 125 psi (862 kPa).
This relief valve needs to be installed on the outlet pipe
from the header as noted in Fig. 14 below.
If required, this needs to be installed in a field-supplied
fitting external to the heater. The valve shall be
installed in a vertical position. Do not over-tighten.
Install the pressure relief valve hand tight plus 1/2 turn.
The valve lever should be tripped at least once a year
to ensure that waterways are clear. If the relief valve
does not function properly, replace it immediately.
PIPE ONTO DISCHARGE SIDE OF PIPING
Fig. 14: Pressure Relief Valve Installed
WARNING: To avoid water damage or scalding due
to relief valve operation, drain pipe must be
connected to valve outlet and run to a safe place of
discharge. Drain pipe must be the same size as the
valve discharge connection throughout its entire
length and must pitch downward from the valve. No
shut-off valve shall be installed between the relief
valve and the drain line.
